LAMP SHADE.

Application filed March 14, 1927. Serial No. 175,153.

to a light supporting structure,and having an ornamental lightdiffusing shade mount-.

ed on said frame. v

A still further object of the inventionis to provide a lamp. shade that consists of a Japanese parasol, from which the apex of the parasol and the supporting handle therefor have been removed, to enable the remaining portion of the parasol, resembling a truncated cone, to be mounted on a suitable supporting frame.

A still further objectof the invention is to provide a lamp shade shaped as a truncated cone and having the entire circumference thereof corrugated or pleated,suitable support bars being secured in the corrugations or pleats to enable the frame to be mounted on a suitable supporting structure.

Other objects of the invention are to provide a lamp shade constructed after the fashion of a parasol, that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation, and facility and convenience in use and general efliciency. f

Y In. this specification and the annexed drawings, the invention is illustrated in'the,

' form considered to be the best,but it is to be understoodthat the invention is not limited to'such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied. I

In the accompanying one sheet of drawlngs Fig. 1 represents a perspective view of a lamp shade constructed in accordance with my invention, being partly broken away to show the method of securing the lamp shade on a suitable supporting frame.

Fig. 2 is an enlarged section taken through the frame to illustrate the method of holding the lamp shade on a supporting frame;

In detail, the construction illustrated in the drawings comprises a wireframe for a lamp shade. The same consists of the upperv ring or hoop land the bottom ring or hoop 2 of greater diameter than the 'upper ring or hoop, connected together by the bars 3.

The shape of'the frame, consisting of the upper and lower rings connected by the supporting bars, issomewhat similar to that of a truncated cone.' As is the usual'practice in the construction of lamp shades, the up per and lower rings and connecting bars would be suitably wound with/tape or ribbon 10 for the purpose of concealing the wire frame, which in time might become rusty ,or discolored, or unsightly, and for the secondary purpose of providing a vbacking to which the lamp shade might be sewed, in order to secure it in a relatively'permanent position on the frame. a

The lamp shade to be mountedv onf the frame'preferably consists of a Japanese or Chinese parasol, from which the apex of the parasol, as well as the supporting handle therefor, has been removed. The type of parasol referred to is onein which ajplw rality of ribs or strips of resilient material 4, formed from wood or steel, radiate from a central point throughout the three hundred and sixty. degrees of a circle. The radial strips are-covered by a circular piece of transparent material 5 such as paper, cloth,

silk, parchment, or the like, so that the supporting strips and covering material form a unitary structure The ends of the radially extended strips. 4 at the point of radial origin are pivotally secured to the end of a handle or shaft, the axis of which is adapted to extend at right angles to the flexible strips, when said strips are in the extended position. The covering material 5 between the radial strips is creased or folded radially,

in the same direction as the strips, in order that said covering material warren-in, uni-, formly, between'the strips 4 when the said strips 4 and'covering material 5 are collapsed into a closed positionsubstantially parallel with the, supporting handle. 'As in conventional parasol or umbrella construetion, a slideringis provided on the shaft, to, which a plurality of expanders are pivotally secured, ,theopposite ends of said ex panders being pivotally secured to theribsf cutting out the apex' or the circular part, at the parasol, I also remove the parasol expanders therefrom, as well as the handle on which the apex of. the: said parasot, as; well" as the expanders, are mounted. After removing the aforesaid parts of the arasol,

the remainder of the parasol comprises a truncated cone open at the top and bottom, having a pleated or corrugated circumference.

In Fig. I I have" shown a lamp shade comprised of: a plurality of flexible ribs; or strips t on which the fabric or paper covering 5 is mounted. The strips are secured to the fabric by means of glue or shellac in order to; hold them in. place thereon. The covering material 5 between the strips 4' is creased or folded so that the entire covering will adjust itself in uniform spaced relation around the entire circumference of the supporting frame. The inner edge of each of the flexible coveringsupporting strips adjacent the upper end thereof is provided With entire circle thereof, and said cord is drawn taut, to hold the shoulders 6 seated on the ring I of thesupporti-ng frame. In addition a thread 9' is passed through the covering' frame.

mg material 10 on the supporting frame and through the draw cord 7. that holds all of the resilient strips 4 in place on the frame. The draw cord 7' that passes through" the upper ends of the strips 4 regulates thev diameter of the smaller end of the truncated cone forming the shade in conformity to. the diameter of the supporting frame; An ornamentalcord 11 also passes through the material 5 which covers thesstrips; f, under and over alternate strips, to assist. in restricting the upper end of the lamp shade to a predetermined diameter, and hence to assist in holding the narrow or smaller dial-metered end of the shade in position on the support- The upper edge of the shade. adjacent Where it is joined to the supporting frame, is enclosed hy' an edging material 12 of ornamental appearance; I have. found thatl'i'y anchoring'the upperendoff the shade to the upper portion 1' of the supporting frame, that the lower end of said frame will hang in graceful lines around the lower ring 2 oftheframe and will assume the same graceful position as'that of a partially opened parasol.

Having thus described this invention, What I new claim and desire to secure by Letters Patent is:

1. A shade shaped as a truncated cone and (iOIlSiStiDg of a covering of pleated formation; strips secured to the covering in line with the pleats, each of said strips havinga shoulder adjacent the inner upper end thereof; means passed through the upper ends of: said strips. to. regulate the diameter of the smaller end of the truncated cone; and a frame shaped to conform to the interior of the shade having means on the upper end. thereof to support the shoulders on the strips of the shade covering.

2; A lamp shade shaped as atruncated cone and consisting of a covering of pleated formation;- strips secured to the covering in line with the pleats;- a frame shaped as a truncated cone to fit within the covering of pleated formation; a draw cord passed through the upper ends of the strips on the coveringto regulate the diameter of the smaller end thereof to effectengagement thereof with the upperend of the frame; and means to detachahly secure said draw cordto the frame; p

3. A; lamp shade shaped as a truncated ce-ne and consisting of a covering. of pleated forn'iation; strips secured to the covering in line with the: pleats, each of said strips having a shoulder adjacent the inner upper end thereof a frame shaped as a truncated cone to fit within the covering of pleated formation; and a draw cord-passed through the upper ends ofthe strips on the covering to regulate the diameter of the smaller end thereof to effect engagement" of the shoulders on the strips with the upper end o-fthe frame. a

4.; A lamp shade shaped as a truncated cone and consistingof a covering of pleated formation; strips secured to the covering in line with. the plea-ts, each of said strips having a shoulder adjacent the inner upper end t'lrcreof a frame shaped as truncated cone to with-in the covering of pleated formation; a draw cord passed through the upper ends of the strips on the covering to regulate the diameter of the smaller end thereofto effect engagement of the shoulders on. the

strips with the upper end of the frame; and

means to detacha-bly' secure the draw cord
